Abstract: 411,359. Bolts; drive-screws. HOFFMANN MANUFACTURING CO., Ltd., New Street, Chelmsford.-(Assignees of Bott, G. R. ; 8, Howes Avenue, Stamford, Connecticut, U.S.A.) Oct. 21, 1933, No. 29222. Convention date, Aug. 2. [Classes 89 (i) and 89 (ii).] The two parts 15, 16 of a ball or roller bearing cage are secured together by self-tapping fasteners 18 which are forced into the material between the pockets for the antifriction elements in such a way as to cut their own threads in the material. The fasteners 18, Fig. 3, have hardened quick pitch threads reversely arranged at their two ends, and a reduced part 23 in the middle to allow for displaced material. The pilot ends 22 of these fasteners take into aligned threadless holes 21 drilled, punched, or moulded in the parts 15, 16. The latter may be of fibrous or resinous material such as " Micarta " or the material known by the Registered Trade Mark " Bakelite," or of metal such as bronze. Fastteners with intermediate spacer bodies thicker than the reversely threaded ends are used to unite thin cage rings in spaced relation. Other fasteners have continuous multiple threads, and, for uniting a thick and a thin cage ring, fastteners with heads fitting countersunk recesses in the thin ring are used.

Abstract: 1,255,673. Automatic voltage control. SPETSIALNOE KONSTRUKTORSKOE BJURO PO ELEKTROBURENIJU. June 10, 1969 [July 19, 1968], No.29249/69. Heading G3R. A voltage stabilizer for an A. C. motor 1, which operates at a considerable distance from its source of supply, comprises a control unit 5 having saturable chokes 6 whose control windings 29 are supplied from a comparison unit 9 which in turn is supplied with signals representative of actual and desired motor voltage. The former parameter is obtained with high accuracy from a transducer 8 having current transformers 10, 11 whose secondary windings 16, 17 are shunted by respective resistors 19, 20 having values chosen to provide a transducer output proportional to and coincident in phase with the voltage across the motor 1. The value of each resistor is dependent on the total resistance of the wire 3 or 4 associated with its current transformer 11 or 10, on the transformation ratio of its current transformer and on the transformation ratio of a voltage transformer 12 whose primary winding 15 is connected across the wires 3, 4. The windings 16, 17, 18 are connected in series to provide a resultant signal which is rectified and smoothed before its application to the unit 9, whose reference signal is obtained from a D. C. source via members 27, 28. A discussion is given of the theoretical basis for deriving the values of resistors 19, 20 and of the vector diagram, Fig. 2 (not shown), relating the voltage across the wires 3, 4, the volt drops in these wires and the voltages across members 18, 19, 20. Diodes 7 in the unit 5 provide an inherent positive feedback. Resistors 19, 20 may be replaced by impedances chosen on the same theoretical basis and having an inductive or a capacitive component according as such a component is present in the supply conductor comprising the wires 2, 3, 4.

Abstract: 411,742. Envelopes. CHAPMAN, D. G., and CHAPMAN & CO. (BALHAM), Ltd., Grange Mills, Grove Road, Balham, London. Oct. 24, 1933, No. 29487. [Class 146 (ii).] In an envelope of the type provided with a pocket for the reception of the closing flap, the inner side flap 14, Fig. 1, is formed with a lateral extension 16 which is folded inwardly upon the flap to provide the pocket for the closing flap 12. The extension 16 may be provided with adhesive at 17 to secure it to the inside of the flap 14, and a slit 21 along the crease line 20 may also be provided to ensure easy access of the closing flap 12 into the mouth of the envelope ; in a modification a V-shaped piece is cut out at the crease line 20. The envelope is completed by gumming the outer side flap 15 and bottom flap 13 over the inner side flap 14. In another form the inner side flap has a width about half that of the envelope front 11, and the width of the lateral extension is about the same as that of the inner side flap. In this case the outer side flap is substantially wider than that shown in Fig. 1, in order to be capable of overlapping the inner side flap. In another form the inner side flap is of inverted L-shape, being formed by a comparatively narrow strip near the hinge between the inner flap and the envelope front, and a broad strip near the envelope mouth. In this case the doubled-in extension is of the same depth as the broad strip of the inner side flap, and the outer side flap is of approximately the same width as that of the envelope front. In all cases the lateral extension may be of greater depth than that of the desired pocket, and the depth of the latter may be limited by a transverse line of adhesive. In the modification shown in Fig. 9, the outer side flap 15 is provided with a lateral extension 16 which is first folded on to the flap 15 and secured by adhesive 17. The narrow inner side flap 14 is folded on to the envelope front 11, and the flap 15 with its extension is then folded over into place and secured to the flap 14 by adhesive 18. The slit 21 is offset from the hinge line 20 in this case by an amount such that, in the finished envelope, the slit will be adjacent to the inner edge of the side flap 14. A line of adhesive 25 may be provided on the extension 16 near the hinge line 20. Specifications 284,539 and 315,500, [both in Class 146 (ii)], are referred to.

Abstract: 156,388. Marks, E. C. R., (Nathan & Co., Ltd., J.). Dec. 1, 1919. Packeting granular materials in tins. - Consists of a compressing, weighing, and packing machine for packing dried milk powder into tins. The machine comprises two inverted and mutually balanced hydraulic rams 1, 2, which are connected by chains 3 attached to eye-bolts adjustably held in the ram-heads 3<a>, which fit into vertical moulds 5 of the same section as tins 6 held for filling in trucks 7,8. Between the rams is a double bin 9, 10 connected by shoots 11, 12 to the moulds 5, and fed through a shoot 17 from an overhead hopper 16, the shoot being connected to a bent plate 14 which acts as a bottom to the bins 9, 10 alternately, so that the powder is fed to the closed bin. Where a predetermined weight of powder is accumulated in a bin, the plate 14 acting as the bin bottom opens downwards to reverse the shoot 17 and to allow its load to fall. For this purpose the shaft 13 of the plate 14 carries counterweighted arms 21, Fig. 13, at the same angle as the sides of the plate, the arms having spring-pressed adjustable catches 23 to engage with catches 32 on pivoted levers 29 carrying adjustable weights 33 and resting on rests 31. The pre-determined weight of powder 'overcomes the weight 33 to release the horizontal arm 21, to reverse the position of the arms and also that of the plate 14. The powder then passes into a mould 5 through a port 34 controlled by a two-part slide 35, 36, the lower part being weighted and hung on the upper part. The lower part 35 is spring-pressed and is raised by the ram head 3<a>, and when raised engages projections on the upper part to raise that past to complete the opening. The material then passes into a tin 6 in a truck 7, 8 centred below the mould by hinged coupling-hooks 39 connected to truck handles 44, these hooks engaging between adjustable V-bolts on the frame. By raising the handles, the hooks 39 can be disengaged to allow the trucks to be moved on rails 45. To relieve the truck of the downward pressure of the ram, a lifting-table 46,'Fig. 5, is provided below each mould, consisting of vertically slidable metal blocks formed with recesses 47 to receive cambars connected by levers 51, 52 to a hand-lever 53 which turns the cam-bars to force the plate 46 upwards to engage the lower sides of the trucks and to force the projecting upper edges of the tins 6 into recesses in fittings 56 in the moulds. After the ram has compressed the material in the tin 6, the table 46 is lowered and the truck moved under a bridge 58, Fig. 3, over a central ram 57, where it is centred by projections 60 thereon engaging with double-ended catches 61 on the bridge. The truck bottoms consisting of loose plates 62 are then forced up by ram 57 to effect the tin 6 over the bridge, when it is pushed off the truck bottom on to rollers 64.
